Car Problematic After Service - No Car No Feedback

I took my car in for service 17/02/2016, on 18/02/2016 as I was driving on the N1 highway at a speed of 90km's as soon as I stepped on the breaks I lost control of my steering wheel as the car started shaking uncontrollably and swerving from my lane to the next. I immediately contacted the service advisor and told them what happened and that I will be bringing the car in, that's when my troubles started. I was told my car would need to go in for wheel alignment on Friday, I was told to return home of which I am heavily pregnant with a dangerous car that wasn't fixed as there is no courtesy car and nothing could be done. Part was ordered and I was not told it had arrived but I had to call and follow up. Shock was fixed but that did not resolve my car issues. I called several times to speak to DP but each time he is unavailable and I am given Sales Manager or Service Manager who have not been useful. I also reported that perfume and sanitary items were ****** from my car when it was in for service which i forgot to remove. On 26/02/2016 took my car into to Jeep to this day 01/03/2016 has not been fixed or assessment done. I called the dealer on 29/02 & 01/03 left message for DP
